Handheld CB Radio Headset Interference Commonly Found in a Vehicle
Hands free CB radio is designed to allow hands-free operation of a motor vehicle without holding the handset close to the car’s dashboard. A recent study showed that more U.S. drivers are using handheld cb radios in their vehicles, which is likely due to the rising popularity of the device among motorists. A CB radio headset can be used as a hand-held device in addition to the traditional in car device. One common problem that has been noted with using handheld cb radios in conjunction with a standard in car device is interference from other electronic devices. This typically occurs if there is an existing plug or outlet close to the headset that is not properly grounded.
Most handheld cb radios will have a U.S. frequency and most in car devices will have a European frequency. These two frequencies co-exist, but it is possible for one frequency to interfere with the operation of another. This is why it is important to ensure that any electrical connections, such as power outlets close to the motorcycle headset, are properly grounded. It may be possible for you to use an additional outlet that has an earth connection for the purpose. However, this usually proves impractical for the purposes of powering any pagers or other devices that could be powered by the CB radio headset.
The simplest solution to this problem would be to install a ground plane amplifier. Ground plane amplifiers are designed to boost the output of a handheld cb radio so that it will not be impacted by external interference. A ground plane amp will have the output antenna feed into a separate amplifier that is designed to properly convert the signal to an electrical signal, without being affected by exterior interferences. There is some variation in the final output of these units so be sure to do some checking before you purchase.
